It is the intent of these specifications to specify the minimum requirement for the furnishing and delivery of One (1) new Compact Track Loader, to be used by the Solid Waste Division of the Public Services Department. This unit shall be new with less than five hundred (50) hours. Unit shall be delivered complete and ready for service, as specified, and shall be equipped with all of the manufacturer’s standard equipment, as advertised, whether or not specifically mentioned in these specifications, in addition to all other equipment and attachments specified herein. 1. ENGINE Engine shall be a 2.8 L, Turbocharged and Aftercooled Diesel Engine, meeting Tier 4 Final and EU Stage V emissions standards. The engine emissions solution shall incorporate Tier 4 Final emissions technology which captures particulate matter by utilizing a wall flow filter design. Engine shall be direct fuel injected, turbocharged, liquid cooled and shall have four cylinders. Engine shall have a total displacement of not less than 171 in3 (2.8 L). Engine shall deliver peak torque of at least 280 lbf-ft (380 Nm) per SAE J1995. Minimum 74 hp The engine shall be equipped with an alternator that has a charging capacity of at least 85 amperes. Glow plugs shall be provided for improved starting in cold weather. Engine Air filtration shall be accomplished via a radial seal air cleaner with a secondary backup filter, as well as a convenient in-cab air flow restriction indicator. The air intake system shall be designed to accept an external pre-cleaner. The machine shall not have any cooling cores or condenser mounted or stacked on top or below the radiator, restricting cooling capability. The engine and hydraulic oil coolers shall have an ambient temperature cooling capacity of 109 degrees F (43 degrees C). The cooling system shall pull air in from the rear of the machine and exhausted through the top of the cooling package, directing it away from the operator and site bystanders. The cooling fan shall not be belt driven, but should be powered by a hydraulic motor that is demand driven (activated by an electrical solenoid) based on climate and heat loads. When fan is active it must maintain constant airflow and fan speed, even under a load that would cause the engine to lug. Reversing Fan must be available to assist in removing material from the rear door intake screen. Must provide both automatic and manual purge modes. The machine shall have an electronic torque management system that automatically destrokes the hystat pump to reduce the chance of stalling the engine during lugging. There shall be no more than two belts driven off the engine. The machine shall have braided, color-coded and numbered wiring harness for easy diagnostics. The machine shall have sealed pin connectors to prevent dirt and moisture infiltration. The machine shall be equipped with a battery that has at least 12 volts and 900 CCA for cold start capabilities in 32 degrees F (0 degrees C) climate. Battery Disconnect switch (master switch) must be available which will provide a basic level of machine security and prevent battery drain during periods of inactivity. Battery disconnect should provide a method to allow a lock to be added for switch lock-out. The machine shall be equipped with a water-in-fuel sensor and in cab indicator. Exhaust airflow and cooling package airflow should be mixed to reduce temperature of exhaust gases leaving the exhaust stack. Machine shall be equipped with an Auto Idle feature which will decrease the engine RPM to low idle after a period of inactivity.
